5 阻止缩放 （Preventing scaling）

<meta name="viewport" content="user-scalable=no, width=device-width" />

6 阻止弹性滚动（Preventing elastic scrolling）

<script>function BlockMove(event) { //Tell Safari not to move the window. event.preventDefault() ;} ...

7 检测屏幕是否旋转（Detect whether device supports orientationchange event, otherwise fall back to the resize event）

var supportsOrientationChange="onorientationchange"inwindow,

orientationEvent=supportsOrientationChange?"orientationchange":"resize";

window.addEventListener(orientationEvent,function() {

alert('HOLY ROTATING SCREENS BATMAN:'+window.orientation+" "+screen.width);

},false);

8 禁止webapp跳转到safari（for ios）

// Mobile Safari in standalone mode

if(("standalone"inwindow.navigator)&&window.navigator.standalone) {

// If you want to prevent remote links in standalone web apps opening Mobile Safari, change 'remotes' to true var noddy, remotes = false;

document.addEventListener('click',function(event) {

noddy=event.target;//Bubble up until we hit link or top HTML element. Warning: BODY element is not compulsory so better to stop on HTML

while(noddy.nodeName!=="A"&&noddy.nodeName!=="HTML") {

noddy=noddy.parentNode;

}

if('href'innoddy&&noddy.href.indexOf('http')!== -1&&(noddy.href.indexOf(document.location.host)!== -1||remotes)) {

event.preventDefault();

document.location.href=noddy.href;

}
